Emergency! Plants drooping, yellowing, & brown spots. [UNSOLVED (see pg. 2)]

mrgibblet · #1 (**permalink**) 10-11-2009, 08:32 AM

I have no idea what could be wrong with these plants.

Heres a picture of them right on the ending of the 1st week point:

Heres a pic of all of them:

Plant 1:

Plant 1 i think is mutated or something, the seed was stuck on one of the lower leaves around half a week into seeding.

Plant 2:

We put 2 aerogarden nutrient tabs in on around friday.
Plant 2 is very yellow and looks like it may be unhealthy... Can any of you tell me what might be wrong with these plants?

Sorry if my post is kinda weird, i just got done shrooming and im disoriented lol.

Is anyone going to help?
The plants have alot of brown spots on them now.

It's almost too late, they're going to die unless we get help quick.

It looks like an over watering problem or maybe Ph? Is it drying out well enough between waterings? Enough O2 in the water?

We made sure it's not overwatering, we have the aerogarden set to Herbs/Basil so the pump turns off for 7 hours, allowing the growing medium to dry out.

We do not know where to get a pH meter, or pH up or down, so it may be pH.

I don't think there's enough oxygen in the water. How much H2O2 should I add to my water?

Also the plants have a lot of brown spots on them now.

Oh yeah, and the reservoir of water smells like sweaty socks, but it doesn't smell too bad.

Could it be drying out TOO much and killing the roots? Root damage can look like over watering... But you'd think that it would wilt...

mrgibblet · #7 (**permalink**) 10-12-2009, 04:16 AM

Okay, should I try putting the aerogarden pump on 24/7?

Also, how much H2O2 should I add to the water, I don't think the plants are getting enough oxygen. We have a fan in there, but the roots arent getting any fresh air.

Bump.... please help!

Aerogardens aren't near big enough to properly grow a MJ plant. They will end up root tangling each other and also quickly outgrow the system. Also, last grow I saw in one of these that was sucessful, he only used one tab at a time, so I'm thinking you nute burned the plants. It's better to undernute than to overnute, because overnute kills em MUCH faster. H2O2 or hydrogen peroxide should be added at the rate of NO more than 1/2 cup per GALLON of res. I'd start at 1/4 cup and work up if it doesn't have a lot of effect.

Hello,

The aerogarden nutrient tabs should not be used to grow cannabis. They tend to burn the crap out of plants, even with only half of a tab.

Your plants should not be given nutrients until around the end of the second week.

It may be too late to save your plants, but here's what you need to do:

Drain your reservoir, and refill it with distilled water.

Around day 15, give your plants proper hydroponic nutrients.

and get a fan pointed and those plants.

Good luck.

Thank you.

I've been using drinking water from my fridge, because I have no distilled water. And today is the exact ending of week 2 (Day 14).

The plant has grown quite a bit, but they still have brown spots on them.

Thanks for all your help.

mrgibblet · #12 (**permalink**) 10-12-2009, 08:49 PM

Also, should I start budding since it's week 2?
I've heard people saying they should have started the budding process on week 2.

I'm thinking I should let them grow a little more, but it will be hard to transplant water once they are real big.

Nute burn. No aerogarden tabs!!! You don't fertilize a seedling.

If there is more than 1 plant in there, they will kill each other shortly.

Define "transplanting water", you lost me there. You have to let the plant at least get to the veg state before you flower it. It's still a seedling.

mrgibblet · #14 (**permalink**) 10-12-2009, 09:01 PM

Okay.

I meant water transplant as in taking the reservoir out and renewing the water in it to keep them healthy.

I think week 3 will be the right time to start budding.

And thank you, I will no longer use aerogarden nutes.

But why are the little leaves so yellow?

LBH · #15 (**permalink**) 10-12-2009, 09:31 PM

They are "burnt". Like a chemical burn, from the nutes

The longer you veg the plant, the better yield you'll get. Is there a reason you want to throw it into flower so soon? Is this one of those "single bud" grows? I'm doing a few plants like that now, to fill the holes I might have when they get under the screen but I'm vegging them for at least 3-4 weeks. 2 nodes, however long that takes.
